Sense of humor

In his article “Save our national sense of humor!”, Garrison Keillor describes how a Domino's Pizza employee recently made a video of her co-worker doing some disgusting things to a sandwich, and how after it was posted on You Tube it “had such an effect on Domino's business that its president, Patrick Doyle, made his own YouTube appearance defending the brand” and the authors of the video were charged with felonies.
Keillor mostly defends the two misguided employees and sees these events as evidence that we are losing our sense of humor. He contends that the internet magnifies our satirical behavior to “an absurd level” with exaggerated consequences, whereas in the real world, it would be just another fart joke.

Although well worded and entertaining, Keillor's article lacks the kind of substance that would get us to ponder his position. He uses mostly anecdotal evidence for his points, stating how “This shakes up some of the road guys, who wonder what the world has come to.” Are we supposed to relate to the road guys? Take their opinion as that of humor experts? The backdrop for his story just doesn't seem to serve his purpose very effectively, aside for highlighting how information technology, including the internet, is a huge part of the nomadic life of some.
 He seems to be writing this article to remind the average American to just cool down and acknowledge that fart jokes and grossing each other out are just something we share as a cultural norm. Yet he brings up roadies, which probably aren't the majority of his reading audience, makes a vague reference to Jonathan Swift (“What Jonathan Swift strove to create in "Gulliver's Travels," the Conover Two brought about with a simple upload”) which, without clarification, will probably go right over most readers' head.
Then for two paragraphs he proceeds to describe his satirical hypothesis on a snowball effect that this allegedly dwindling sense of humor would end up having: “And then we will hear about guerrilla skirmishes between corporations, Domino's sneaking out a video purporting to show rats running through a Pizza Hut and the Hutites responding with one of a coven of witches explaining the Wiccan meaning of the dots on the domino.” Because it is speculation and written as such, he doesn't really do anything to convince readers that his thesis is valid (i.e. that the two employees didn't do anything terrible, the internet is just so powerful that we end up taking everything on there too seriously)

At least part of Keillor's reasoning could be convincing if this article wasn't so random and devoid of supporting evidence that isn't merely hearsay, the opinion of a specific population, or speculation. As it is, it just seems like a rant. Considering that the topic is fairly contentious, the reader would expect a firm position with a well-supported rhetoric. “It's just snot” the case.
